kudlinski Posted February 11, 2008 Share Posted February 11, 2008 This is my first post so please excuse my ignorance. Im looking to buy a second hand compresser to help in my iminent landy rebuild. Im going to look at one tomorrow which is driven by a honda petrol engine. It is described in good working order but is 12 years old. What should i check for / look at? Its made by clarke and is 9cfm if that makes any difference. Thanks for looking. Paul Quote Link to comment Share on other sites More sharing options...
simonr Posted February 12, 2008 Share Posted February 12, 2008 If it develops ait pressure - it's probably good enough. Generally it's the motors which die on compressors. With a petrol engine - it should go on for centuries! Take something like an impact wrench which uses a lot of air with you. See if it keeps up. You should be able to judge roughly the cfm by the duty cycle you can run the gun at. Si Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 12, 2008 Share Posted February 12, 2008 If it's a Honda GX engine they will run forever, if you buy it run a shot of redex through the petrol to clean it out and it'll be sweet. Quote Link to comment Share on other sites More sharing options...
kudlinski Posted February 12, 2008 Author Share Posted February 12, 2008 Thanks for the advice. Once the landy has been rebuilt i will be using it predominantly for spraying (unfortunatly my barn has no electricity). Would a 9cfm 50 litre tank be man enough for spraying small (14ft) sailing dinghys? Quote Link to comment Share on other sites More sharing options...
Guest mortus Posted February 12, 2008 Share Posted February 12, 2008 its a little bit small for spraying i think, you could spray small panels, but once your tank is low on pressure it wont make a good job. Quote Link to comment Share on other sites More sharing options...
paintman Posted February 12, 2008 Share Posted February 12, 2008 It MIGHT be able to keep up with one of the smaller full size guns but it is going to be marginal. 9cfm is probably its displacement. Free Air Delivery (FAD) is the important figure & will be lower. Have a look at Machine Mart & others at sprayguns to see what their cfm requirement is.

Mr Bean Posted February 14, 2008 Share Posted February 14, 2008 Did you buy it in the end? Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted February 14, 2008 Share Posted February 14, 2008 For what its worth, I have heard that older tanks rust out from the inside (due to water vapour in the air). In the end you start getting pinhole leaks from the tank and its effectively useless. I have no experience of this, but there may be some truth to it which justifies avoiding older units (tanks, at least). Cheers, Al. Quote Link to comment Share on other sites More sharing options...
